having a for sale sign up at their house doesn't bother me anymore as i have their name anyway. They can run. But they can't hide.
Tip: Always charge extra for 'initial clean' regardless of how convincing your potential customer is for a regular cleaning service to at least cover the extra time spent on initial cleans.Customers are getting more devious nowadays like taking down and hiding the 'For Sale' sign in the shed just to get their windows cleaned prior to selling as a lot of window cleaners stop cleaning once they see the 'For Sale' sign go up
There`s a name for these types of customers and the name is problem,if he dosen`t want it done on a sensible cycle don`t do it,you`ll be putting off your regular work to be at there beck and call.
